Elantra MD (2010-15) :: RPM Hanging At 3000 At Standstill / Couldn't Drop To Idle
I had to make a left hand turn very quickly into a gas station. I moved in 1st gear and accelerated quickly (went around 3,200 RPM). When I stopped in the parking spot, clutch disengaged, brake pedal engaged, the engine was still spinning at 3,000 RPM!!!! I waited until the engine calmed itself down to idle RPM but it was stuck at 3,000 RPM.
Something wrong with the accelerator? I put the car back in 1st gear and rocked forward a couple of inches so I can put a load on the engine. I put the gear back in neutral and the engine calmed down to idle RPM. Something was stuck? Bad computers? Bad design?
Elantra XD (2001-06) :: Shifts To Overdrive Only After Running 3000 RPM For A Mile
2001 Elantra shifts to overdrive only after running 3000 rpm for a mile. Then at other times it shifts to overdrive ok. fluid is ok Sometimes putting the shifter into neutral with the car rolling and putting it back into drive will get it to upshift.

I've got an automatic transmission 2002 elantra 2.0 that I purchased in 2009. About a year after owning it a weird problem developed that I've just sort of lived with since. Between 25-40 mph my RPMs occasionally "bounce" persistently by an amount between 500 (mild) and about 1000 (severe). There's a bit of fluctuation insofar as what RPMs/speeds it happens at depending on outside temperature and how warm the engine is (higher temps correlate with this issue happening at higher RPMs and a more pronounced fluctuation), but it's a consistent issue every time I drive. It *seems* like my car is always trying to push down the revs, hits a certain low point depending on the gear/speed, then jumps up just a bit only to edge back down. Lather, rinse, repeat. It's not simply a display problem as I can feel and hear the engine revs changing.
No fluctuations at idle. Above 3000 RPMs it's ALWAYS smooth sailing. When I'm actively accelerating there's never a problem, even if my acceleration stays in the revolution problem range. The car is never in danger of dying, but if the cruise is engaged (ESPECIALLY in the 25-30 MPH range at operating temp) the car shudders uphill - I assume this is because the RPMs dip a bit too low for the gear the car is in. If I press the throttle the car responds normally. This bouncing RPM issue itself NEVER causes the car to shift gears in response, and if it's happening and the car DOES shift everything works fine until it goes back to trying to maintain RPMs in the problem range. When it happens I usually just increase speed by 5MPH and it goes away, though if the car is warm and the speed limit doesn't allow me to go fast enough to get out of the problem range it just does the same thing at the slightly higher RPMs.
When the problem started my car threw an OBD code - I didn't read it myself and brought the car to a random service shop who SAID they changed the throttle position sensor, and the code was gone, but a few days later it was doing the same thing without throwing a code. I tried changing the fuel pump thinking it was a fuel delivery problem, but that didn't solve anything. I put seafoam in the fuel system monthly so I'm fairly certain that fuel system gunk isn't an issue. The symptoms haven't changed AT ALL during the 6+ years this has been happening.
The kicker is that a few years ago I found a SUPERB mechanic - the first one I've ever actually trusted to be not only competent but also honest. Described the problem and even demonstrated it to him. When I brought in my car to have the struts and mounts replaced he spent two days trying to figure out what was causing the RPM issue too... and couldn't nail it down.
Possibly related: after starting the car - regardless of how long it's been running - there's a brief delay between pressing the gas pedal and the engine responding. Delay seems *slightly* longer the colder it is outside, but it's never more than a second and a half. No further delays unless I shut the engine off and turn it on again. Replacing the fuel pump didn't affect this matter whatsoever.
Elantra XD (2001-06) :: Engine Is Revving Up To 3000 RPMs When In Park Or Neutral
2002 Elantra engine is revving up to 3000 rpms when in neutral or park. I changed the Throttle Position sensor and it went right back to revving up. Code read P0121. What might be causing this? Seems like I get one thing fixed and then another code shows up..

View 3 RepliesElantra XD (2001-06) :: Idle Will Bounce From 1.5k To 3k Exactly
So this problem came about after I changed the timing belt on my wife's 05' elantra.
The idle will bounce from 1.5k to 3k exactly and continue this for as long as the car is on. Some times it will stay at some point within that range for around 2 seconds then continue to bounce.
I checked the belt today, and it seems to be tight enough but not to loose either...maybe I screwed the timing up? But would that cause this problem?
Here is what I have done:
Replaced the IAC valve
Cleaned the MAP sensor (no MAF sensor on this engine, that I know of...)
Checked and cleaned the spark plugs
Cleaned all electrical terminals
Checked the resistance in the throttle control sensor
Checked for vaccum leaks with carb cleaner
Cleaned PCV valve (3 times)
Replaced Air filter
Probably a few things I am missing in there, but nothing has been a success.
Elantra XD (2001-06) :: Won't Idle Down Below 1500 Rpm
02 elantra 138418 miles. Before I cleaned throttle body engine idled fine, but know I can't get engine to idle below 1500 rpm, check engine lite is on, went to advance auto parts, he pulled code, he said idle air control stuck, i am hoping there is something i can do before spending $ and replacing it.

So, I have a 2016 Elantra SE Auto w/ 26k miles, I have 1k miles life until my next oil change.
Since about Saturday, whenever I accelerate, around 3k RPM - 4k RPM it's running/ sounding really rough! Not sure what's causing that, I checked my air filter earlier that day & put it right back in, also put in some HID lights in. I thought maybe the containment cover or gasket around the filter wasn't seeded properly, but everything checks out. I'm pretty car savy, so I know this isn't normal for brand new cars. Doesn't seem like it's loosing power, I still get pretty quick throttle response when I really gas it!

View 12 RepliesElantra XD (2001-06) :: Intermittent Missing At Idle
I have a 2003 Elantra GLS that has two issues that may be related. The first one the engine will shut off for no apparent reason. Doesn't matter how fast, or if the a/c is on or not. I used to be able to start it right up after I pulled over, now I have to wait about 15 seconds. Starts up fine and runs like nothing happened. There is no particular time frame when it will shut down. Maybe once a month, then happen twice in a week.
Second issue is when I have to stop at a red light and have the a/c on, it seems to have an intermittent miss, meaning after it does miss it idles fine for a while and then misses again. It seems like a miss to me, feels like the car almost shuts down but catches itself and will idle fine until next miss. If I turn off the a/c I do not feel it miss. If I have the a/c on and put it into neutral, it does not appear to miss near as much.
The check engine light has come on twice for a day or so and then goes out. Car runs fine when it does. Below is what I have done since I purchased the car used at 104,000 miles. current mileage - 117,000
* changed timing belt, transmission fluid, brake fluid, changed oil at 104,000 miles when bought.
* installed new radiator recently
* installed crankshaft sensor (due to error code when checked)
Other than that, car runs great, accelerates good, idles good
Elantra XD (2001-06) :: Won't Idle When Cold / Will Stall
My 05 Elantra 2.0, 5 speed won't idle when cold til I drive it a few hundred feet. It will stall. Only then will the idle rise to what it's supposed to be. Is there some sort of cold idle sensor/module that needs replacing?
View 2 RepliesElantra XD (2001-06) :: Deep Rattling Sound Along With Very Low Idle
When I am driving my elantra (engine warm), say I pull up to a red light or I am in a 'drive thru' my RPM's will go to under 500 and normally go under 400 which causes the whole car to shake and sound like it will stall. The car also has the issue with the Air Conditioning on that makes the vehicle have a deep rattling sound along with the very low idle which follows with my lights dimming or lightly flickering.

Elantra XD (2001-06) :: 2004 - AC Only Works At Idle And Low Speed?
As the title says the 2004 Elantra only has a/c at idle and low speed. It started with the a/c stopping, and a mechanic gave me as story about the wiring going to the compressor being faulty. He jumped a wire from the drivers side fan to the compressor. It turned on the compressor and I had cold air again. or so i thought.
Now, it's cold at idle or slow around town stuff, but as soon as I get on the highway it stops working and blows outside temp air. Is it the compressor? If not, I wondered if the fan (drivers side) is turning at highway speeds and not back on till I stop.
Elantra XD (2001-06) :: 2003 - Rough / Jerks At Idle
Below is a link to a video showing what my 2003 Hyundai Elantra is doing. It is idling very rough (Jerks at idle) and can actually be heard in the exhaust. I think it may be miss firing?? Does not do it at speeds over 60. Under 60 it can be felt at times, but only at low RPMs. [URL] ....
View 16 RepliesElantra XD (2001-06) :: 2004 - AC Not Blowing Cold At Idle
04 Elantra GLS, AC works great and is icy cold at higher RPMs but gets hot when stopped at idle or driving low speed. Fan works, refrigerant level is correct. At low idle speeds the compressor just shuts off. A few minutes later or if the engine speed picks up it will engage and start cooling again. AC tech didn't think it was the compressor since the pressure difference between the high and low sides was in the correct range. Has this issue fixed by replacing the pressure sensor/switch on the high pressure side? It doesn't look like there is a low pressure side sensor that I can see.
View 2 RepliesElantra XD (2001-06) :: High Idle / IAC Motor Revving Up And Down
I had some problems with my Elantra and I fixed (or tried to) them all this weekend. I needed a new IAC motor, the motor was reving up and down and I tested it, then changed it. I needed a fuel injector and changed that. I needed a lower thermostat housing and changed that.
These changes resulted in the following problems. The vehicle now revs at a high idle all the time at approximately 3000. What are the causes of this?
I know that when I was burping the coolant system (changing out all the hoses and the thermostat housing) I got antifreeze sprayed all over the top of the motor.
Here is the problems that I have now. Didn't have these before.....
The engine idles at or about 3000 rpm. Constant from startup until shutdown. It idles down when you shift it into gear but that is because of the strain on the motor with the brake used.
The transmission is now having problems shifting from 1st to 2nd. I checked the fluid, its good. There is however antifreeze on top of the transmission by some sensors. Do these sensors have anything to do with the shifting?
Elantra XD (2001-06) :: 2004 GLS - Sudden Rough Idle Under 1k RPM
I have an '04 Elantra GLS with 274k on it. I've been caring for it myself with basic maintenance; that said, I changed the oil in it about 100 miles ago. Halfway through my drive home it started to idle rough under 1k rpm.
I've noticed a lot of other Hyundai's have the same issue. What would be/is the most COMMON cause of this? Timing belt? Basic tune up? I moved a state away from my local shop and I refuse to go to a Midas/Jiffy/ect.
